How does PHP handle global scope when instantiating objects from strings?

When instantiating objects from strings in PHP, the global scope can be handled by using the fully qualified class name, including the namespace if applicable. This ensures that the object is instantiated in the correct scope, even if the code is being executed within a different namespace. 

// Example of instantiating an object from a string in PHP with proper global scope handling

$className = 'MyNamespace\MyClass'; // Fully qualified class name
$obj = new $className();
